[0040] The technical solutions of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0041] In the description of the embodiments of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "top" and "bottom" is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "arrangement" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0042] Refer to the attached Figures 1-6 , this embodiment provides a multifunctional measuring instrument for the butt joint of precast square piles, which is used to measure the perpendicularity of the upper square pile 10 or the misalignment distance between the two square piles after the upper square pile 10 and the lower square pile 11 are butted and before welding, or to measure the weld height and fullness after the upper square pile 10 and the lower square pile 11 are butted and welded. The multifunctional measuring instrument specifically includes: a folding measuring rule 1, a first pile abutting plate 2, a second pile abutting plate 4, a weld measuring block 3, and a sliding rod 5. The folding measuring rule 1 is a mature product. Integrating it with other structures in this instrument is mainly for convenient carrying and practical use. The model of the folding measuring rule 1 can be selected by those skilled in the art according to actual usage requirements. The specific structure will not be elaborated here. However, in order to accurately describe the positions and connection relationships of other structures in this instrument, according to the existing structure of the folding measuring rule 1, the side of the folding measuring rule 1 used to abut the object to be measured is defined as the measuring surface 1.1, and the side opposite to the measuring surface 1.1 is named the non-measuring surface 1.2; the bottom surface of the first pile abutting plate 2 is connected to the non-measuring surface 1.2 of the folding measuring rule 1, and the top end is connected to the weld measuring block 3. A plurality of sliding rods 5 are inserted through the weld measuring block 3 and can slide along the thickness direction of the first pile abutting plate 2; the second pile abutting is parallel to the plate surface of the first pile abutting plate 2, its bottom end is connected to the weld measuring block 3, and it can move along the thickness direction of the first pile abutting plate 2 on the weld measuring block 3.

[0043] During the butt joint construction of precast square piles, first sink the lower square pile 11 into the pile hole and extend the top of the lower square pile 11 a certain distance outside the foundation. Then hoist the upper square pile 10 above the lower square pile 11, unfold the folding leveling rule 1, use the measuring surface 1.1 of the folding leveling rule 1 to abut against the side wall of the upper square pile 10 to detect the verticality of the upper square pile 10. Then fold up the folding leveling rule 1, use the plate surface of the first pile abutting plate 2 to tightly abut against the side wall of the lower square pile 11, slide the second pile abutting plate 4 to tightly abut against the side wall of the upper square pile 10, and calculate the misalignment distance between the upper square pile 10 and the lower square pile 11 in the horizontal direction according to the relative position relationship between the first pile abutting plate 2 and the second pile abutting plate 4. When the verticality is qualified and the misalignment distance is within the tolerance range, the welding work of the upper square pile 10 and the lower square pile 11 can be carried out; after welding, align one end of the slide bar 5 with the plate surface of the first pile abutting plate 2, use this plate surface of the first pile abutting plate 2 to tightly abut against the side wall of the lower square pile 11, and align the position of the weld measuring block 3 with the weld 12. Since the weld 12 protrudes horizontally from the side wall of the lower square pile 11, the weld 12 will push the slide bar 5, causing the slide bar 5 to slide along the thickness direction of the first pile abutting plate 2 and extend from the other end of the weld measuring block 3. The weld height can be calculated by observing the extension distance of the other end of the slide bar 5, and the fullness degree of each point of the weld along the circumference of the precast square pile can be judged by evaluating the extension states of multiple slide bars 5.

[0044] As described above, since the weld 13 protrudes horizontally from the side wall of the lower square pile 11, the thickness of the weld measuring block 3 must be less than that of the first pile abutting plate 2 to prevent the first pile abutting plate 2 from being unable to tightly abut against the side wall of the lower square pile 11. Therefore, in this embodiment, it is stipulated that the weld measuring block 3 has opposite first side surface 3.1 and second side surface 3.2, and the first side surface 3.1 and the second side surface 3.2 respectively correspond to the directions of the two side plates of the first pile abutting plate 2, but at least one of them is concave with respect to the plate surface of the first pile abutting plate 2, that is, the thickness of the weld measuring block 3 is less than that of the first pile abutting plate 2, so that when the first pile abutting plate 2 tightly abuts against the side wall of the lower square pile 11, there is a gap or just abuts against the weld 12 between the side surface (which can be the first side surface 3.1 or the second side surface 3.2) of the weld measuring block 3 close to the weld 12 and the weld 12.

[0045] To improve the convenience of measurement, the outer wall of the slide bar 5 is provided with a first scale 5.1, and the first scale 5.1 is dispersed along the axial direction of the slide bar 5, and the weld height can be directly calculated by reading the first scale 5.1; moreover, limit blocks 6 are respectively arranged at both axial ends of the slide bar 5, and the aperture of the through hole of the slide bar 5 on the weld measuring block 3 is smaller than the cross-sectional dimension of the limit block 6 to prevent the slide bar 5 from slipping off the weld measuring block 3.

[0046] To fully measure the weld fullness, it is preferred to arrange multiple rows and columns of sliding rods 5 on the weld measurement block 3. When the first abutting pile plate 2 abuts tightly against a side wall of the lower square pile 11, a weld corresponding to this side wall fully squeezes these sliding rods 5. According to whether the elongation degrees of the other ends of these sliding rods 5 are all within the tolerance range of the weld height, it can be judged the fullness degrees of each point in this weld. If it is unqualified, repair welding is required.

[0047] On the other hand, referring to the appendix Figure 2 , a sliding groove 7 is provided on the weld measurement block 3. The length direction of the sliding groove 7 is the same as the thickness direction of the first abutting pile plate 2. A sliding block 8 is configured on the second abutting pile plate 4; the sliding block 8 can slide in the sliding groove 7 or be fixed in the sliding groove 7 under the restriction of the clamping component 9. The relative position of the second abutting pile plate 4 and the weld measurement block 3 can be fixed through the clamping component 9, that is, the relative position of the second abutting pile plate 4 and the first abutting pile plate 2 is fixed, so as to facilitate measuring the relative displacement degree of the second abutting pile plate 4 and the first abutting pile plate 2, and then obtaining the misalignment distance between the upper square pile 10 and the lower square pile 11.

[0048] Referring to the appendix Figure 2 , the clamping component 9 includes a clamping block 9.1, a clamping groove 9.2 and a sliding button 9.3. The clamping block 9.1 is configured inside the sliding block 8 and can move along the width direction of the sliding groove 7 and extend out of the sliding block 8; the clamping groove 9.2 is configured on the inner side wall of the sliding groove 7 for clamping and fixing the clamping block 9.1; a long through hole 8.1 is configured on the sliding block 8, and the sliding button 9.3 passes through the long through hole 8.1 and is connected to the clamping block 9.1. By sliding the sliding button 9.3, the telescopic movement of the clamping block 9.1 inside and outside the sliding block 8 can be realized, and the clamping or separation of the clamping block 9.1 and the clamping groove 9.2 can be realized. When the two are separated, the sliding block 8 can move in the sliding groove 7, and then the second abutting pile plate 4 can move along the thickness direction of the first abutting pile plate 2.

[0049] Preferably, there are two groups of clamping blocks 9.1 arranged oppositely. Each clamping block 9.1 is respectively connected to a sliding button 9.3. The adjacent ends of the two groups of clamping blocks 9.1 are connected by a spring 9.4. The separated ends are respectively clamped to the clamping grooves 9.2 on the two inner side walls of the sliding groove 7. When the two sliding buttons 9.3 are approached to each other, the two clamping blocks 9.1 approach each other and retract into the sliding block 8. At the same time, the spring 9.4 is compressed, and the second abutting pile plate 4 and the sliding block 8 can slide. After letting go, under the action of the spring 9.4, the two clamping blocks 9.1 move away from each other and the two sliding buttons 9.3 move away from each other, and the clamping of the clamping block 9.1 and the clamping groove 9.2 can be automatically realized. During implementation, the shape of the sliding button 9.3 can be configured according to specific requirements and is not specifically limited here.

[0050] To improve the convenience of measurement, a second scale 7.1 is configured at the top of the sliding groove 7. The second scale 7.1 is dispersed along the thickness direction of the first abutment plate 2. The relative displacement between the second abutment plate 4 and the first abutment plate 2 can be directly calculated by reading the second scale 7.1, and then the dislocation distance between the upper square pile 10 and the lower square pile 11 can be obtained.

[0051] Furthermore, for rapid measurement, the following configuration can be made: the first abutment plate 2 and the second abutment plate 4 have the same thickness. In this way, the dislocation distance between the upper square pile 10 and the lower square pile 11 can be directly obtained only by reading the second scale 7.1, without further calculation based on the thickness difference between the first abutment plate 2 and the second abutment plate 4, which can greatly increase the measurement efficiency.

[0052] Compared with the prior art, the beneficial effects of the present invention include: this instrument integrates functions such as weld measurement, verticality measurement, and upper and lower pile dislocation distance measurement, which can reduce the amount of measuring tools carried during construction, is convenient for turnover use, and has simple measurement operations.

[0053] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.

[0054] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art of this technology, several improvements and refinements can be made without departing from the principles of the present invention, and these improvements and refinements should also be regarded as the protection scope of the present invention.
